JOHN GEORGE DIXON, OF BIRKBY, ENGLAND.

DETONATOR HOLDER R CLIP FOR USEIN FOG RAILWAY SIGNALING.

I I SPECIFICATION forming part of Letters Patent No. 527,480, dated October 16, 1894.

Application filed January 18,1894. serial No. 497,253. (No model.) Patented in England December 9, 1893, No, 23,771.

I To aZZ whom it may concern:

Be it known that 1, JOHN GEORGE DIXON, a subject of the Queen of Great Britain and Ireland, residing at 98 Norman Road, Birkby, in the county of York, England, have invented certain'new and useful Improvements in Detonator Holders or Clips for Use in Fog Signaling Apparatus on Railways, (for which I I have obtained Letters Patentin Great Britain,

No. 23,771, dated December 9, 1893,) of which the following is a specification.

This invention relates to improvements in holders or clips for detonators for use in fog signaling apparatus on railways.

In most forms of mechanical fog signaling apparatus, the object of which is in substitu- 1 tion of or as an auxiliary to the fogmen now employed, some sure and easy method must I be employed of placing the detonator on the rail. The detonators are usually contained in a magazine.

My improved holder or clip consists of a piece of tin (or any other metal may be employed) about the same width as the diameter of the detonator. In stamping out the holderlips or projections are stamped out at 1 the higher level end. Two or more three sided cuts (or two sided in the case of a triangular obstruction piece) are made in the lower level end and bent upward at right angles, the upper part touching the higher level piece, preventing the possibility of the angular portion of one holder from being forced I into the corresponding portion of the next below it in the magazine. The lower level end ofthe holder is that which is clipped by the jaws or forceps or other equivalent ofthe mechanical fog signaling apparatus.

The great advantages of higher and lower level ends of holders are (the detonator being on the higher one) that while the detonator is in position on the rail the jaws or other equivalent of the main apparatus are below rail level and out of reach of harm or the wheels of the locomotive or carriages, and,

furthermore, where a number of detonators are in. amagazine each one must be forced into the same position to be in line with the jaws or forceps for engagement to be placed on the metals. There are two points of contact or bearing, therefore, in holders. The higher level end of one holder is supported by the detonator below it, and the lower end next the detonator of the upper holder bears on the upper level end of the underneath holder.

My holder is applicable to any form of mechanical fog signaling apparatus, whether automatic or non automatic, or whether operated by the signal wire orseparate lever in I the signal box.

In order that my invention may be better understood and more readily carried into effect I will proceed to describe the drawings hereunto annexed.

The same letters refer to the same parts in the several figures.
